From the very incomplete manner in which the Count De Castelnau de- 

 scribed many of the insects in M. Gory's collection, I have thought it useful 

 to add figures of the head and thorax of the three following species described 

 by him, from the type specimens now in Mr. Hope's collection. 



Athyreus excavatus, Laporte, An. Art. ii. p. 103 (Juvencus, Dej.). Cayenne. 



Tab. XXII. fig. 9. Caput et pronotum supra visa. 

 Athyreus bicolor, Laporte, An. Art. ii. p. 103. New Grenada.

Obs. Athyreus recticornls, Gu6rin, Iconogr. du R^gne An. Ins. p. 83, from 

 Swan River {Mus. Gory), is identical with Bolboceras hastifer, Bainbridge. 



Obs. The insect placed in M. Gory's collection, with the label of Athyreus 

 porcatus, De Laporte, Anim. Artie, t. ii. p. 103. no. 6, (Athyreus Senegalensis, 

 Dejean,) is a new species of Bolboceras, from Senegal. 



Species added subsequent to the reading of the Paper.
